Disk cartridge

A data storage cartridge for a data storage disk drive has a marker including a latent illuminance material such as phosphor. A matte material on the cartridge or within the marker diffusely reflects charging light that is not absorbed by the latent illuminance material in the marker. This reduces noise and signal pollution in the light then emitted by the latent illuminance material. Accordingly, an accurate decay time can be determined. The decay time is checked to provide identification of different types or generations of data storage cartridges or provides a secure keying mechanism for authorized access to proprietary software.

Use of matte materials to reduce signal pollution in cartridge detection circuitry

A cartridge for a magnetic disk drive has a rigid shell and a flexible door which covers an opening through which read/write heads engage the recording medium. The flexible door is guided outside of the shell to an open position as the cartridge is inserted into the drive. A projection on a flexible arm in the drive catches a hole in the flexible door to open it as the cartridge is inserted into the drive. The door along the outside of the cartridge conserves space so that the recording medium can be large for a given form factor drive.

A system and method for applying a thick layer of luminescent emissive material, such as phosphor, to a substrate, such as a data storage cartridge, is provided whereby a luminescent emissive material is mixed with a binder, the mixture is dispensed onto a mesh screen placed over a substrate, and the mixture is then pushed through the mesh screen and applied to the substrate at a predetermined thickness. The predetermined thickness of the deposited phosphor layer is preferably between about 8 and 12 mils.

Storage disk cartridge

A cartridge for a magnetic disk drive has a clamping mechanism which is actuated as the door to the cartridge is closed when the cartridge is removed from the drive. The door covers the opening through which the cartridge is accessed by read/write heads. When the cartridge is removed from the drive, the mechanism of the present invention clamps the recording disk against the cartridge shell to prevent rattle, which might otherwise damage the recording disk.

Cam mechanism to clamp magnetic disk against cartridge shell

A cartridge for a magnetic disk drive has a rigid shell and a flexible door which covers an opening through which read/write heads engage the recording medium. The flexible door is guided outside of the shell to an open position as the cartridge is inserted into the drive. A projection on a flexible arm in the drive catches a hole in the flexible door to open it as the cartridge is inserted into the drive. The door which opens along the outside of the cartridge conserves space so that the recording medium can be large for a given form factor drive.

A cartridge for a disk drive has a rigid shell with two keying grooves along the top and bottom edges of one side of the cartridge. These mate with projections on the cartridge receiving slot in the drive. One of the grooves extends deeper into one planar surface of the cartridge than the other groove. This prevents insertion of the cartridge with any other orientation of the cartridge than the correct orientation.
